To all wh-om tmay concern:

.'Be it lmown, that PAUL' .WILHELM FUNGK, a citizen ofV Germany, residingin Stuttgart,.Germany, have invented a certain lnew land useful Improved Machine for YCtratingDough, of which the following is a specification.

' The-invention relates to amachine for breaking up dough'into small pieces which vwhen dried are sold for thickening soup. .For thislpurpose thedough in a kneaded condition is rubbed `against andfforced through asieye.

the invention, Va product of uniformL dimensions and pleasing appearn anceV is produeed'by a machineof .very simple operation, which also may ..be oon- According, to

f nected WithV other machines requiring auniform conveyance of small pieces of dough.

lThe accompanying `drawing shows an eX- ample pf a machine 'according tothe invention.' Fig, lis a ,vertical section, Fig. 2 isa section throughfther main `rubbingv member,

and Fig. 3 is a yplan of the .base ofthe hopper of the machine. Y

f On the-frame of theniaehine isa pedestal 1 in which are mounted al horizontal shaft 2,

driven by a belt pulley, and alverti'cal shaft 3 Which carries ,thelv Working 4parts. The shaft 3 is Jrotated by thev 'shaft '2 through a pair of'bevel Wheels 4c. The sieve 5 has the vform of an ordinary bakers sieve and rests,

' so 1as tobe easily remoYed, en supporting ring and isheldin position against anangle iron ring v8 fastenedto the Ypedestal lbybolts 7 :extending between saidsupportingrmg 6 andV angle iron 8.., An arm'lO, preferably of wood, rotates over the .base 9 of the sieve and is fastenedto` a hub '1l from Whiehla 'pin' 38 gprojectsinto ;a groove39 of the shaft 8 ,the lowerV en d o f which` is,,sereW-threaded'.y saidhub beingiyertieally Vadjustable by Va pair 'of nuts f1.2 tru'ponl the shaft 3, which engage the upper; and lower endS'LreSDeetiVely, of .said hub, 'A cover 13: prev'entsthe'lub'rif v4cant which may;` run, out v of V:the 'bearing the pedes tal V,1 from .dropping Y on to the AsshoWn inFig. Zthe'lo'vver surface of thefarm 'l0 V isvbeveledtoward one'sideand as saidja'rmrotate's only the beveled surface which presses the dough againstthe elastic f sieve 9- exerts anyfrublzingV action Whilf .The plate the other part `which rotates behind in'- clined edge vloosens the 'particles that remain adheringtothe sieveand fdrives them `be fore it and so. continuallynlean's the sieve',

A hopper-14 carried by the/pedestal ly hasV a delivery'spout1 depending from its lower endV to form,v a continuation thereof',f A

coarsemeshed sieve 15 extendsfacro'ss .the

lower end of Vthe'delivery"spout and has Va from vthehopper to thel spout. A second V- plate 37 is seated VWithin,the spout uponV the intermediate shoulder toY serve as aV catch plate for the .material vdelivered from the hopper throughthe passage afforded bythe. ,cut-.away portion of the plateBG.Y A 'recess 22 is :thus formed l br-teje en theplates' p36 l and 37.-. I i

137 is cut away, as shown b. dottedlines in Fig. 8,'to. straddle the Vertical shaft ,3 YandV to afforda passage for the material which falls upon the plate 37 through thecut-away portion ofthe plate lf'lhe .plates 36 and S'Zfar'e arranged in the hopper vvith theirV cut-away portions in staggered relation'.-

vA blade 3.1L, carried by the jvertical shaft 3,.,rotates above and close tothe baseplate 3.6 of theVr hopper andan arm -35 rotates inVr the'recess22 between the base plate 36 and thecateh :plateV 37.` 'Another arm 16' on rthe Vertical shaft lrotates betweenthe catch plate 3T "andthe sievel.

' lThe pieces of dough placed vin the hopper,

bev of any size,ar e Vswept around bythe/ blade 34; upon the vbase plate jand ashear-like"actionfis: exerted upon y' them; between@ blade. Seeed Off@ :edge of the cutawayporjtion of thefplate 36e-s they pass'throu'ghtheopening afforded by said eutyaway portion, fllhusthefy are .out intoVV smaller; piec'es'. Theyfthengfall upon vthe 'catch Aplate`37, are swept varoundupon saidY plate by the 351,' andV passthrough'the 'eut-.away portion of the plate 37to thesieve i The annv 16 thenfsweeps them around i on the sieve Yl5, and forces them through CIK the said sieve into the funnel 23, from which they are delivered into the c line sieve 5. They Vare then forced through the sieve 5 by the arm l0.

It is of importance that tlierubbing arms i Y over the sieves should always drive and disintegrate the pieces of dough in a loose condition. Anycongestion makes the Work of the' machine 'more diflicult and' causes the doughrto be forced throughV the meshes of the Vsieve-s. with'. a considerable pressure, vvherebypieces of irregularlength'and unpleasing jagged appearance are"Y formed.

This drawback is obviated by ythe dough v being disintegratedgradually into small pieces, and especially bythe fact that the material can only pass from the hopper into the rubbingdevice inv uniformly smallquantities, CorrespondingtoI the rsize of the re ces's22.
